摘　　要：文章旨在探究日粮添加纤维素酶(Cellulase,CEL)对康县太平鸡生长性能、血清生化指标及肉质品质的影响。试验将600羽1日龄康县太平鸡公雏随机分为4组,每组10个重复,共计150羽,试验由0~21 d、22~42 d和43~105 d三个阶段构成,试验日粮在各阶段基础日粮中添加0、60、120和240 mg/kg的CEL。结果显示,与对照组相比,120和240 mg/kg的CEL组太平鸡末重分别显著升高4.74%和4.95%(P<0.05),平均日增重分别显著升高4.91%和5.11%(P<0.05),料肉比分别显著下降3.83%和5.12%(P<0.05),此外,CEL对太平鸡采食量无显著影响(P>0.05)。240 mg/kg的CEL组太平鸡血清葡萄糖(GLU)和丙二醛(MDA)含量显著降低(P<0.05),超氧化物歧化酶(T-SOD)能力显著提高(P<0.05),120和240 mg/kg的CEL组太平鸡血清生长激素(GH)及胰岛素(INS)含量显著提高(P<0.05),CEL对太平鸡血清甘油三酯(TG)、总胆固醇(TC)、胰岛素样生长因子I(IGF-I)含量及谷丙转氨酶(ALT)、谷草转氨酶(AST)活性均无显著影响(P>0.05)。240 mg/kg的CEL组太平鸡胸肌L*值和粗脂肪含量显著提高(P<0.05),剪切力显著降低(P<0.05);120和240 mg/kg的CEL组太平鸡胸肌a*值显著提高(P<0.05)CEL对太平鸡胸肌b*值、pH值及粗蛋白质含量均未产生显著影响(P>0.05)。结论:添加纤维素酶能提高太平鸡生长性能并改善肉质,综合考虑各项指标,以240 mg/kg的添加剂量最佳。The aim of this study is to investigate the effects of adding cellulase(CEL)to feed on the growth performance,serum biochemical indicators,and meat quality of Kangxian Taiping chickens.6001-day-old male Taiping chickens from Kang County were randomly divided into 4 groups,each consisting of 10 replicates and a total of 150 chickens.The experiment was conducted in three stages:0~21 days,22~42 days,and 43~105 days.CEL at doses of 0,60,120,and 240 mg/kg was added to the basic diet of each stage as the experimental feed.The results showed that compared with the control group,the CEL groups at 120 and 240 mg/kg significantly increased the final weight of Taiping chickens by 4.74%and 4.95%,respectively(P<0.05),significantly increased the average daily weight gain by 4.91%and 5.11%,respectively(P<0.05),and significantly decreased the feed to meat ratio by 3.83%and 5.12%,respectively(P<0.05).In addition,CEL had no significant effect on the feed intake of Taiping chickens(P>0.05).The serum GLU and MDA levels of Taiping chickens in the CEL group at 240 mg/kg were significantly reduced(P<0.05),and the T-SOD ability was significantly improved(P<0.05).The serum GH and INS levels of Taiping chickens in the CEL groups at 120 and 240 mg/kg were significantly increased(P<0.05).CEL had no significant effect on the serum TG,TC,IGF-I levels,ALT and AST activity of Taiping chickens(P>0.05).The L*value and crude fat content of Taiping chicken breast muscle in the CEL group at 240 mg/kg were significantly increased(P<0.05),and the shear force was significantly reduced(P<0.05);The a*value of Taiping chicken breast muscle was significantly increased in the CEL groups at 120 and 240 mg/kg(P<0.05).CEL had no significant effect on b*value,pH value,and crude protein content(P>0.05).Conclusion:Adding cellulase can improve the growth performance and meat quality of Taiping chickens.Taking into account various detection indicators,the optimal dose is 240 mg/kg.
